George Coupland is a Director of the Max Planck Institute for Plant Breeding Research in Cologne and a Professor of Genetics at the University of Cologne.

His research group studies how plant development is influenced by environmental signals. He uses Arabidopsis thaliana as a model system, and recently developed its relative Arabis alpina as a comparative perennial system. His group has defined mechanisms by which plants detect and flower in response to daylength and how annual and perennial life histories diverge during evolution.
